Not all, some very small units are in the 40's, they are just much less common than the big boys due to the applications they use them for.
The other way around this of coarse would be a diesel genset but they are all over the map eff. wise as well.
Also, no offense but 50lbs verses 200lbs is a consideration. Also smaller is usually cheaper which is another measure of efficiency.
And a motor that is SMALLER than required could be operated continously at its most efficient peak area regardless of the speeds I drive, If I had a genset that operated peak eff at full speed, it would be recharging my batteries all the time because I rarely travel full blast and have lots of stops. Whereas a motor sized just big enough to toot me along at 25mph would always be operating at its peak efficiency and would improve my range significantly enough that I would never have to worry about it. (I don't drive 200miles one way)
